COMBINATION-TOOL FOR SQUARING PURPOSES.

SPECIFICATION forming part of Letters Patent No. 683,254, datedSeptember 24, 1901. Application filed July 12, 1900. Serial No. 23,320.(No model.)

To ctZZ whom it may concern.-

Be it known that I, ANDRE DELIN, of Everett, in the county of Middlesexand State of Massachusetts, have invented certain new and usefulImprovements in Combination- Tools for Squaring Purpose to be Used inGonnection with a Level or Plumb-Rule, of which the following is aspecification.

My invention consists of making a metal blade to be attached andinserted into an ordinary level or plump-rule, making a combination-toolwhich may be used for both leveling, plumbing, and squaring purposes.

The advantages of my improvements are compactness, accuracy, and asaving of labor by the use of the tool.

The accompanying drawings illustrate my invention, in which- Figure 1represents the tool with the blade inclosed and in use only for levelingand plumbing purposes. Fig. 2 is a cross-section through the center ofthe tool and showing the blade of the square half drawn out. Fig. 3represents the blade drawn out and set in position ready for use eitherfor squaring, leveling, or plumbing purposes. Fig. 4 is a detail drawingof the method of fastening the blade into the headpiece of the level.Fig. 5 represents the metal head and cap which holds the blade inposition when in use and covers the opening when blade is inclosed inthe level. Fig. 6 represents the metal blade before being pushed intoposition for squar- Fig. 7 shows the blade pushed into and held in placeby the metal head of the level.

Similar letters refer to similar parts of the drawings. a

A represents a metal head with a slot cut in the center, through whichthe blade of the square is inserted when not in use and into which theblade is fastened when used for squaring purposes.

B shows a side view of the cap, which covers the slot when blade isinserted into level and is fastened into slot by means of bent pieces ofmetal pushed into the slot and having, a slight spring.

0 C are slots out into metal blade and which are pushed into the slot inthe metal head A and hold the square in position while in use.

D D are two metal flanges turned in opposite directions and preventingthe blade of square being drawn out of slot at A.

E is a metal blade which is figured on both sides for measuring purposes'and when fastened into metal cap A is used for squaring purposes. Theblade is drawn out, as shown in Fig. 2, until the flanges D strike themetal head A. The blade is then turned at an angle of forty-five degreeswith the level, and the slots 0 C are pushed into metal head A, as shownby Figs. 3 and 6.

I am aware that prior to my invention tools have been used for bothleveling and squaring purposes, and therefore I do not claim such acombination broadly; but

What I do claim as my invention, and desire to secure by Letters Patent,is-

1. The combination with a level provided with a pocket, a blade slidablymounted in said pocket, a cap on the end of the level partially closingsaid pocket, and means on one edge near one end of said blade forengaging said cap to hold the blade in position at right angles to thelevel,substantially as described.

2. In combination with a level rovided with a pocket, a blade slidablymounted in said pocket, a cap on the end of the level partially closingsaid pocket, means on one edge near the end of said blade for engagingsaid cap to hold the blade in position at right angles to the level,andmeans for preventing the withdrawal of the blade from the level,substantially as described.

3. In combination with a level provided with a pocket, a blade slidablymounted in said pocket, a cap on the end of said level partially closingsaid pocket and provided with slots, and tongues provided on oneedgenear one end of said blade for engaging in said slots when the blade ispartially withdrawn from the level and turned at a right angle thereto,substantially as described.

4-. Incombination with a level provided with a pocket, a blade slidablymounted in said pocket and having on one edge near one end one or moreengaging devices and upturned portions, and a cap on the level havingslots therein for the passage therethrough of the blade whereby onwithdrawing the blade, said upturned portions will engage the under sideof said cap to prevent the withdrawal of the blade and upon turning thelng, means carried by the blade for engageand a slide-plate providedwithmeans for en gaging said cap, whereby to close the opening thereinwhen said blade is within the pocket, substantially as described.

In testimony whereof I have affixed my signature in presence of twowitnesses.
